The Drug Enforcement Agency is a criminal justice agency headed by an Administrator appointed by the US President and should be confirmed by the Senate (United States, Staffing, n.d.). Its main mission includes the enforcement of laws and regulations on controlled substances and to “bring to the criminal and civil justice system of the US” everyone who participates in growing, production, processing and distribution of controlled substances (Hewgley, 2009, para. 24). In order to carry out its mission, the agency disseminates information uncovered with the intelligence sector (Hewgley, 2009). DEA offices situated in the US are called domestic offices (The Drug Enforcement, 2007).
Before the establishment of the DEA under the Department of Justice, several agencies fought against drug trafficking with some simultaneously performing the same functions, namely: a) under the Department of the Treasury - 1) Bureau of Internal Revenue (1914-1921), 2) Narcotic Division, Bureau of Internal Revenue (1921-1927), 2) Narcotic Division, Bureau of Prohibition (1927-1930), 3) Bureau of Narcotics (1930-1968); b) under the Food and Drug Administration – 1) Bureau of Drug Abuse Control (1965-1968); c) under the Department of Justice – 1) Bureau of Narcotics and Dangerous Drugs (1968-73) (Records, n.d.).
